SPECIFICATION forming part of Letters Patent No. 793,575, dated June 27, 1905.

Application filed December 13, 1904:, Serial No. 236,764.

To all whom/ it may concern.-

Be it known that I, JOHN W. FAnssLnR, a citizen of the United States, and a resident of Moberly, Missouri, have invented certain new and useful Improvements in Flue-Beaders, of

my invention as seen looking in the direction indicated by the arrow 1 in Fig. 2. Fig. 2 is a view in elevation at right angles to Fig. 1 as indicated by the arrow 2 in Fig. 1. Fig. 3 is a sectional detail on the line 3 3 of Fig. 2 and looking in the direction indicated by the arrow 2, said view being on a plane parallel with Fig. 1. Fig. 4: is a perspective of one of the expanding-jaws. Fig. 5 is a sectional detail of thcflue and flue-sheet after it has been beaded, said view being on a greatly-reduced scale compared with the other views.

Referring to the drawings in detail, the mandrel 6 is cylindrical in cross-section and adapted to [it in the end of the fine 7 after the flue has been expanded into the flue-sheet 8. A

and 16 extend outwardly from near the upper 4 ends of the jaws, and the heads 17 and 18 extend outwardly and upwardly above the semicircular beading faces, there being deep square or rectangular recesses 19 and 20 in said heads, and a strong rubber band 21 is embedded in these recesses to hold the jaws yieldingly in position. Aknurled head 22 extends upwardly from the mandrel 6 above the expanding-jaws 11 and 12, and a shank 23 extends upwardly from the head. The opera- 5 tion is obvious.

What I claim is 1. In a flue-beader, a mandrel transversely slotted to form-a wedge and to form seats for the expanding-jaws; expanding-jaws fitting in the slot against the wedge; beading-surfaces carried by the expanding-jaws; and a rubber band embedded in the expanding-jaws to hold the jaws in position; substantially as specified.

2. In afiue-beader: amandrel transversely slotted to form seats for the expanding-jaws and to form awedge between the expandingjaws; expanding-jaws mounted in the seats and having beveled upper ends fitting the wedge and having semicircular beading-sur- 5 faces extending outwardly from their upper ends, and having recesses above the headingsurfaces; and a strong elastic band fitting in the recesses to hold the expanding-jaws in position; substantially as specified. 7 I

In testimony whereof I have signed my name to this specification in presence of two sub scribing witnesses.
